Product Description

Hanna BL983329-2 Mini TDS Controller is a compact, high-performance panel-mounted instrument engineered for precise, continuous monitoring and control of total dissolved solids (TDS) in water and process streams. Designed for reliability in industrial, laboratory, and water treatment environments, this controller operates within a measurement range of 0 to 999 ppm (mg/L), making it ideal for applications requiring tight control of low to moderate TDS levels.

The BL983329-2 is built to support both automatic and manual dosing operations, providing flexibility for a wide range of process requirements. In automatic mode, the integrated dry contact relay is triggered when the measured TDS value exceeds the user-defined setpoint, enabling real-time activation of dosing pumps, solenoid valves, or other control systems. This ensures that corrective actions such as dilution, drainage, or chemical dosing are carried out efficiently without constant operator intervention.

The controller features a clear, high-visibility LCD display protected by a transparent cover, allowing operators to easily monitor readings while safeguarding the interface from dust, splashes, and harsh environmental conditions. A multicolor LED indicator further enhances usability by providing quick visual feedback on operational status, alarms, and dosing activity.

For seamless integration into larger control systems, the device is equipped with a 4–20 mA analog output, enabling direct communication with PLCs, SCADA systems, and other industrial automation platforms. This ensures accurate data transmission for centralized monitoring and process optimization.

The BL983329-2 incorporates automatic temperature compensation within a range of 5 to 50°C (β = 2%/°C), ensuring consistent measurement accuracy even when process temperatures fluctuate. Manual calibration via an integrated CAL trimmer allows users to maintain precise alignment with standards, supporting long-term measurement reliability.

Additional control features include an adjustable dosing relay (maximum 2A, 250VAC / 30VDC, fuse protected) and an over-dosing timer that can be set between 5 to 30 minutes, providing enhanced safety and process control. The fixed EC to TDS conversion factor of 0.5 ensures stable and predictable readings across standard applications.

Constructed with a fire-retardant, splash-resistant enclosure, the controller is designed for durability and safe operation in demanding industrial environments. Its compact dimensions (83 × 53 × 99 mm) allow for easy panel mounting, making it suitable for space-constrained installations.

Widely used in water treatment systems, laboratory automation, chemical processing, HVAC systems, and manufacturing operations, the Hanna BL983329-2 Mini TDS Controller provides reliable and efficient TDS monitoring and control for continuous processes.
